In this video clip we'll be calculating board footage. To calculate board footage we're first going to take the thickness we're going to multiple that width, we're going to multiple that by the length and then we're going to divide all of that by 12. Now on this board we have a thickness of 1", the width is 9 1/2" which you actually round that up to 10" and then we have a length of 24". Since all of our values are in inches we actually need to convert this to 144 and once calculated out that will equal 1.66 board feet. Now if my board was exactly 1 foot long by 1 foot wide by 1" thick then it would be actually 1 board foot.
